What this setup essentially represents is “How many 8s can we take away from 32 before hitting 0?” Which in turn can be reframed as “How many 8s fit into 32?” This can be captured in the expression 32 / 8. As we can see from the problem, we can take away 4 8’s before hitting 0, so that gives us the equation 32 / 8 = 4

Given:

The area of a rectangle is 99 square yd.

Length of the rectangle = 7 yd more than twice the width.

To find:

The dimensions of the rectangle.

Solution:

Let x be the width of the rectangle. Then, length of the rectangle is:

Length=2x+7

Area of a rectangle is:

A=length\times width

A=(2x+7)\times x

A=2x^2+7x

The area of a rectangle is 99 square yd.

2x^2+7x=99

2x^2+7x-99=0

Splitting the middle term, we get

2x^2+18x-11x-99=0

2x(x+9)-11(x-9)=0

(x+9)(2x-11)=0

Using zero product property, we get

(x+9)=0 and (2x-11)=0

x=-9 and x=\dfrac{11}{2}

x=-9 and x=5.5

Width of the rectangle cannot be negative. So, x=5.5 yd.

Now, the length of the rectangle is:

Length=2x+7

Length=2(5.5)+7

Length=11+7

Length=18

Therefore, the length of the rectangle is 18 yd and the width of the rectangle is 5.5 yd.

ehidna [41]
Ok so if we have five dollars per shirt, and if the number of shirts we buy is x, we have 5x dollars for the price. there is also a $40 design fee, so that adds 40. we do not need to pay 40 for every shirt, just once for the whole group, so we have 5x+40 as our answer

Find the angle of elevation of the sun from the ground to the top of a tree when a tree that is 10 yards tall casts a shadow 14
Hitman42 [59]

Answer:

The angle of elevation of the sun from the ground to the top of a tree is 36^{\circ}.

Step-by-step explanation:

As given

The sun from the ground to the top of a tree when a tree that is 10 yards tall casts a shadow 14 yards long.

Now by using the trignometric identity .

tan\theta =\frac{Perpendicular}{Base}

As figure is  given below .

AB =  Perpendicular = 10 yards

BC =  Base = 14 yards

Putting all the values in the trignometric identity .

tan\theta =\frac{AB}{BC}

tan\theta =\frac{10}{14}

\theta =tan^{-1}(\frac{10}{14})

\theta =36^{\circ}

Therefore the angle of elevation of the sun from the ground to the top of a tree is 36^{\circ}.
